Abstract
Various vascular filters are provided. In one aspect, a vascular filter is provided that includes a tubular sleeve and a core positioned in the sleeve that is axially deployable therefrom. A shape-memory wire is spiraled around the core and has a first portion unfurled from the core to define a hoop. The hoop is expandable from a retracted shape to a expanded shape when the core is deployed from the sleeve. A filter is provided that has a first end coupled to the core and a rim coupled to the hoop. The integration of the hoop with the shape-memory wire provides for excellent tip flexibility with enhanced resistance to structural failure.
